The HP320AA000340 is a compact self-contained LED emergency exit sign light fixture from the HARPER 320 lineup, equipped with an autonomous Self-Test diagnostic matrix. Formed within a white self-extinguishing polycarbonate body shell with a silk-screened PMMA diffuser, it offers a standardized 20-meter directional visibility range. Operating under a standard Maintained framework, it uses front-facing multicolor functional indicators to report diagnostic system status and backup battery integrity in real-time, pulling prolonged safety illumination from an onboard LiFePO4 core during electrical failures.
